Lasers do not produce ionizing radiation that damages DNA
Your concern about laser DNA damage has been discussed and argued since medical lasers were first used in the early 1980"s.
We know that X-ray and other forms of nuclear radiation emit ionizing radiation which can damage intracellular DNA and cause metaplastic or neoplastic changes which can cause cancer.
Lasers and light wavelengths are not ionizing forms of radiation. They kill cells that we want to remove, but there is no evidence that laser radiation (to my knowledge) causes neoplastic chnages in irradiated tissues.
This has been discussed many many times in the past 20 plus years and the consensus of most experts is taht lasers are safe.
